The  Potter Waterflow  Alarm  Switch Model  VSR  is  a  vane  type  waterflow  switch  for  use  on  water  mist  systems. It is UL Listed and FM Approved for use on  steel pipe; schedules 10 through 40, sizes 2″ through  3″ (50 mm through 80 mm). LPC approved sizes are 2″  through 3″ (50 mm through 80 mm).

The  VSR may  also  be  used  as  a  sectional  waterflow  detector  on  large  systems.  The  VSR  contains  two  single pole,  double  throw,  snap action  switches and  an  adjustable,  instantly  recycling  pneumatic  retard.  The switches are actuated when a flow of 10 GPM (38  LPM) or more occurs downstream of the device. The  flow  condition  must  exist  for  a  period  of  time  necessary to overcome the selected retard period.

The VSR switches and retard device are enclosed in a  general purpose, die‐cast housing. The cover is held in  place with two tamper resistant screws which require  a  special  key  for  removal.  A  field  installable  cover  tamper switch is available as an option which may be  used to indicate unauthorized removal of the cover.
